Abstract:
The disclosed induction heating cooking device includes a boiling-over detection portion which is adapted to reduce heating output from an inverter to a pre-set value if the amount of change of a capacitance detected by a capacitance detection portion from a reference value (Vo) is equal to or more than an output reduction threshold value (ΔV2), and further is adapted to stop heating, if the amount of change is equal to or more than an output stop threshold value (ΔV3). In this case, the output stop threshold value is provided for each of the plurality of the electrodes, which can absorb impedance variations in the plurality of the electrodes formed through pattern printing using conductive films, thereby uniformizing their sensitivity to boiling over in any directions.
